1. Converts fractional division into integer division. For example, convert 0. 12÷0.03 into (12 ÷ 3) ÷ (0.010.01), so that fractional division can be converted into integer division.

2. Using the law of quotient invariance, the divisor and dividend are expanded or reduced by the same multiple at the same time, so that both the divisor and dividend become integers. For example, in the above example, we expand the divisor 0.03 and the dividend 0. 12 by 100 times at the same time, and get 3 and 12, so that fractional division can be converted into integer division.

3. Calculate the quotient by integer division. For example, in the above example, we can get the quotient 4. Reduce the obtained quotient to the original decimal form. For example, in the above example, we convert quotient 4 into 0.4 and get the final result.

4. By this method, accurate results of fractional division can be obtained more quickly, and errors caused by manual calculation can be avoided. This simple operation method can not only help us better understand the calculation method of fractional division, but also improve our calculation speed and accuracy.

5. The simple operation of the fifth grade fractional division is an effective calculation method, which can help us get accurate results faster. The basis of this simple operation is to convert fractional division into integer division by using the law of integer division and quotient invariance, so that fractional division can be calculated like integer division.

The fifth grade mathematics curriculum scope volume one

1, understanding of numbers: learning integers, decimals and fractions, including their meanings, properties and operation methods. Digital operation: learn various operation rules and methods, including addition, subtraction, multiplication and division, multiplication and mixed operation. Geometry: learn all kinds of geometric figures, such as rectangles, squares, circles, triangles, etc. , and understand their properties, area and perimeter calculation method.

2. Data analysis: Learning the methods of data collection, collation, description and analysis can solve simple practical problems. Probability statistics: learn the basic concepts and methods of probability statistics, and be able to conduct simple random investigation and data analysis.

3. Through the study of these contents, students can master the basic knowledge of mathematics, improve their mathematical literacy and lay a foundation for their future study and life. At the same time, the first volume of the fifth grade mathematics course also pays attention to cultivating students' thinking ability and problem-solving ability, so that students can gradually form mathematical thinking mode and improve their mathematical application ability in the learning process.
